Impulse Backpack

Built for ambitious days out — from all-day trail runs to alpine approaches — the Impulse handles whatever you throw at it across 20L and 30L sizes. Robic HD 210-denier ripstop nylon with a 2,500mm PU coating keeps your gear dry without adding weight, while a Tool Blade system and daisy chains secure ice axes and hardware when the terrain gets serious.

• 210-denier Robic HD ripstop nylon with carbonate PU coating delivers a 2,500mm water column rating — genuinely weatherproof without a rain cover on most Southern storm days
• Over-the-top zipper opens the main compartment wide for easy access to layers and larger gear; four internal mesh pockets plus a hydration sleeve keep everything organized
• Thermoformed back panel and contoured shoulder straps are padded, quick-drying, and stay comfortable on long hot days — tube ports on both sides let you run the hydration hose left or right
• External Tool Blade and daisy chains secure ice axes, trekking poles, or other hardware; removable compression cord with toggle cinches the load when you're running light
• Available in 20L and 30L — the 15L ships with a lightweight waist strap while both the 20 and 30 come with a removable low-profile padded hip belt with a zippered stretch pocket on each side
